Car Stops With AC On – AC Compressor Could Be Blocked
Website design By BotEap.comOne of the main causes of a car stalling with the A / C on is a seized compressor. If there is screeching, smoke, stagnation, and hot air comes out of the vents every time the air conditioner is turned on, it is a good assumption that the compressor has locked out. If there is only one belt squeaking but the car won’t stop and the air conditioner cools down, the belt or tensioner is most likely worn out. The most likely cause of a car not idling high enough and sometimes stalling with the A / C on without any of the other issues mentioned may be an IAC (Idle Air Control) engine.
